Rotating Detonating Engines Can Enable Practical Hypersonic Planes
by Brian Wang from NextBigFuture.com on (#6HHCD)
The main problem holding back reusable hypersonic planes is that traditional ramjet engines become very inefficient over mach 2 while hypersonic engines do not work well below mach 4. There is the need to solve the hypersonic speed gap between mach 2 and mach 4. Rotating Detonating Engines can be more efficient up to mach ...
